Is 500W Power Supply Enough For i7 950+RX 480 Nitro?

Get_rekt41 · Feb 17, 2017

Hello Community!
I having a dell T3500 system with i7 950 installed on it. And its psu have 1x6pin but rx 480 has 1x8pin
So i Decided to upgrade my psu.
Is 500w psu enough for these specs?
CPU=i7 950 3.06ghz
Ram=Corsair value select 1333mhz 4x 2gb sticks.
GPU= Sapphire Rx 480 8gb Nitro+ OC
HDD= 1 TB WD Blue
SSD= 120 GB samsung 840
Fans= 2x 120 mm fans.
Dell Server motherboard lga 1366

The Nitro+ OC is a 225W GPU.... and i7-950 is a 130W CPU.
Around ~100W for the balance of everything else
That's ~455W absolute max (theoretical) load. Pairing the 8GB 480 with an i7-950 won't allow the 480 to reach it's max performance (and therefor, power draw).

A true quality 500W might just do it, although I'd be inclined to look at a minimum 600W.

Quality is where it matters though, not just the wattage. What PSUs were you looking at?

What's your budget (for a PSU) and location?

Yet I haven't seen Bottlenecks while playing these games= Rise of the tomb raider, Resident evil 7,watch dogs 2,Mafia 3.
gpu is on 100% load and by afterburner it shows gpu draws off 130-140 watts at full load.

Well i m from Pakistan And planning to go for Corsair CX 500 or GX 550.
What do you say about it?

Barty1884 · Feb 17, 2017

I'd be very surprised if that's the case, but if it is - good for you.

Avoid to CX500 and CM GX 550, they're not very good - and not likely to hold up running those components for long.

What's your budget? Looking at a few stores, Pakistan seems to lack quality PSUs below 18,000 / $180 USD.

Barty1884 :

Well my budget can be 60$ saying accordingly to my country,i can get brand new corsair vs 650watt under this but still looking for suggestion.Which psu model I should go for?. If 550watt is enough that would be better. Let me know the Psu Model. I will make my budget for it.

If you can get a EVGA 500W PSU that should be more than enough.

Barty1884 · Feb 17, 2017

Honestly, the VS lineup is comparable in quality (and actually a little worse) than the CX.

Is there anything available from SeaSonic, XFX or Super Flower in Pakistan? Other than those, it really depends on the specific models.
For Corsair, the RMx, RMi, AX, HX linups are quality. The VS and CS are not. Some of the CX are pretty good (the newer CX450 CX550, CX650), but the older ones (430, 500, 750) are not.

Lopperuk :

I assume you're talking the 500B/500W? If so, they really won't be 'more than enough'.

They'd be 'barely enough', and a little risky since they're really not very good all things considered.

Yes,there Are Seasonic psu here .Antec also but never seen xfx,super flower around here. So i better go for Seasonic?

Corsair Rm series are expensive and might go out of budget.

Barty1884 · Feb 17, 2017

Yes, SeaSonic you can trust on brand alone. Anything SeaSonic 600W+ (S12II 620W if you can find it) would be ideal. 550W at a stretch.

Barty1884 :

ok Thanks

madmatt30 · Feb 17, 2017

To be fair the cooler master gx550m isn't a bad psu really.

Steer clear of the corsairs unless you can source the newer cx550m , the only antec I'd consider would be the truepower classic or the 2015 vp550f model (don't confuse it with the vp550p)

But yes as barty says a seasonic is just a safe bet full stop, I disagree on the total wattage though ,with everything stressed (which isn't going to happen) you may just hit 400w at the utmost max IMO.

madmatt30 · Feb 17, 2017

Be aware you need to update your motherboard to the latest bios version a17 or it won't boot with a 480

Also be aware that these cards have no analog output (as in no VGA) so make sure your monitor has dvi or HDMI connections.

Barty1884 · Feb 17, 2017

madmatt30 :

You're right, the GX 550 isn't as bad as the CX, and my statement grouped them together.
The revision fo the GX line was decent (vII?), but I don't think the originals were too great at all - and it wasn't clear if this was V1 or V2.

While I'm probably a little over-cautious on my wattage calcs, those Nitro+ cards are crazy. Officially they're 225W( so 75W over reference specs to begin with, but some have been pulling nearer 250W*.

*I wouldn't have thought the OP would be able to stress it enough with an i7-950 to result in those increased wattages, but they're claiming >80% GPU usage

lol good one, I've got the EVGA 500W running fine on i7 7700k and a GTX 1080 so it definitely is more than enough

Barty1884 · Feb 18, 2017

Lopperuk :

Modern 91W CPU + 180W GPU vs 1st Gen i7 (130W) and a GPU that could pull 250W

Yup, those are the same thing :lol:

The 500W and 500B are budget orientated PSUs, just because you are running high end hardware on there, doesn't mean you should

On what Barty said, I will add this aswell: Newer components not equal more power required

Barty1884 :

Yeah it does, else it wouldn't work.
